NONLINEAR PHASE SPEEDS AND DEPTH INVERSIONS

摘要

Experiments were conducted in a laboratory facility under with a fixed bathymetric profile containing a single bar. A hybrid data set was collected consisting of remotely sensed wave data combined with modelgenerated wave amplitude profiles. The data is used to test the improvements in depth retrieval through the use of a nonlinear composite dispersion that is applicable in arbitrary water depths. The dispersion relation relates the wave properties with the local water depth and the results suggest that inclusion of nonlinearity improves depth estimation on shallow water.
